报告摘要:
Frost formation induces considerable energy and economic loss in diverse industrial applications, including power line, aircrafts, refrigeration and heat pump systems. Endowing anti-frosting functionality to surfaces has been highlighted to mitigate frosting-induced issues as a passive strategy with no additional energy consumption. In this talk, we present the recent progress on developing anti-frosting functional surfaces in our research group. First, fabrication of the wettability-controlled surfaces, such as superhydrophobic, superhydrophilic, and slippery surfaces, are presented. Their anti-frosting characteristics is discussed in terms of frost retardation and defrosting performance. Second, development of superhydrophobic-superhydrophilic hybrid surfaces is presented to promote synergistic effects of superhydrophobic and superhydrophilic surfaces, thereby achieving excellent anti-frosting functionality. Finally, the strategy to apply the rationally designed anti-frosting surfaces to heat exchangers is also discussed. We believe that our results can provide a guideline to further enhance the anti-frosting performance of target surfaces.
